Segmental Method for Determining
Center of Gravity

Once center of gravity (COG), or center of mass, is determined
for the body or group of segments moving as a unit, you can treat
the COG as a single mass resting on that point. Since the subject's
segmental stats are not known, an average of these stats (see
Body Segment Data) may be used. Knowing the actual weight of
the subject or the segments is unnecessary since percentages
are used.
